There are no limits to space and there are no limits to time (both past and future).
There are limits in time for our Universe. Our universe was born with the Big Bang about 13.8 billion years ago and it will be destroyed in another Big Bang many billion years from now. ( I estimate the lifetime of our Universe at 100 billion years, so we have a while to go.) Our Universe replaced our predecessor universe and our Universe will be replace by our successor universe. There are also limits to space in our Universe because our Universe is surrounded by a cold plasma shell. That reflects most radiation to produce the cosmic background radiation that fills our Universe. I am not sure you gain anything by assuming that the laws of physics “exists”. The laws of physics as I understand them are merely human attempts to explain how our Universe and the Cosmos operates. It is our Universe and the Cosmos that exists. Our Universe did not exist prior to the Big Bang and it will not exist after the Big Bang that will destroy it. However, our successor universe will exist and our predecessor universe did exist prior to the Big Bang. I define the Cosmos as everything that exists, has existed in the past and will exist in the future. I believe that there was a time, long, long ago, before there was anything when there was nothing, just empty space. This to me seems perfectly logical.

I can only repeat what I said before: 'My position is that the idea that you can explain the origin of "a universe from nothing" is absurd.' Either you have pre-existing laws and substrate -- which is not 'nothing' -- or the universe just "pops" spontaneously, and laws, etc, are just descriptions of observed regularities in whatever has "popped". You don't have many other options. The other popular option (in both religion and physics) is that the universe is eternal and no "popping" is needed. Some are eternal and infinite and others are eternal and cyclic. This is true, of course, and changes the question (slightly) - "Why does the eternal universe, and its laws of physics, exist?" A conspiration made by the numbers 0, 1, 2, 3, 8, sqrt(2), e, pi, i, gamma, 24 and 808,017,424,794,512,875,886,459,904,961,710,757,005,754,368,000,000,000, tries to make you believe so. (The big number is the number of elements of the Monster group, and is related to the Moonshine conjecture; which gives light on some shortcut between number theory and physics, and groups, and measures, ...). Anyway, if that is true, that has to be justified by the self-introspecting universal machine. And that gives a piece of formalism (S4Grz1, Z1*, X1*), so we get some light and testing abilities. Liz, could you please remind me which hat you put during month with "r". For the purposes of discussion with Mr Ross, it has to be a "primary materialist" one. I don't think he's ready to discuss other ideas (yet). -- You received this message because you are subscribed to the Google Groups "Everything List" group.
